Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Facebook Friends interface not returning Friend ID


While implementing the onlinefriendsfacebook interface i noticed that the function

void FOnlineFriendsFacebook::ReadFriendsUsingGraphPath(int32 LocalUserNum, const FString& ListName)

is not returning any id's, due to wrong key while iterating over the friend results. Specifically the line 275 in OnlineFriendsFacebook.cpp it should be const FString Id([user objectForKey : @"id"]); and NOT const FString Id([user objectForKey : @"ObjectID"]);

By changing this it will now return the correct friend ID. I did some digging around at Facebook developer portal and haven't seen any reference to ObjectID when fetching friends. they have been using the key "id" since api v 2.0.

I know this is easy to correct if you are using the source code engine. But for people that are on the precompiled version this might be a problem.

Best regards.
